Add revert resized server functional negative tests
Add revert resized server functional negative tests

The negative tests of revert resized server API are not covered enough
in functional tests. We want to add the conflict tests
of when this API runs in the unexpected state of server.
* Case of revert resized server API, the server status must be VERIFY_RESIZE.
